Abstract: Generally, the present invention provides a variable thickness gate oxide anti-fuse transistor device that can be employed in a non-volatile, one-time-programmable (OTP) memory array application. The anti-fuse transistor can be fabricated with standard CMOS technology, and is configured as a standard transistor element having a source diffusion, gate oxide, polysilicon gate and optional drain diffusion. The variable gate oxide underneath the polysilicon gate consists of a thick gate oxide region and a thin gate oxide region, where the thin gate oxide region acts as a localized breakdown voltage zone. A conductive channel between the polysilicon gate and the channel region can be formed in the localized breakdown voltage zone during a programming operation. In a memory array application, a wordline read current applied to the polysilicon gate can be sensed through a bitline connected to the source diffusion, via the channel of the anti-fuse transistor. More specifically, the present invention provides an effective method for utilizing split channel MOS structures as an anti-fuse cell suitable for OTP  memories.

Abstract: The efficiency of an exothermic autoclave leach process is increased by increasing the retention time of the solids fraction in the feed slurry over that of the liquid fraction. This is achieved by flashing the contents of the first oxidative autoclave compartment to a flash vessel, with the underflow therefrom passing to a thickener and the underflow from the thickener being fed to the autoclave feed tank or any tank upstream of the feed tank.  Exothermic heat generated in the first compartment of the autoclave is abstracted in the flashing process. Additionally portions of the overflow from the thickener are returned to the feed tank and fed to the autoclave discharge tank.
